    Abstract: The material is obtainable by a) reacting an aqueous dispersion of waterglass and a pigment with a strong acid and/or waterglass with a pigment-containing strong acid to give a pigment-containing silica hydrogel, the pigment being characterised in that it scatters, absorbs or reflects infrared radiation of wavelength 3 - 10 mu m, b) substantially freeing the pigment-containing silica hydrogel thus obtained from ionic constituents by washing out with water, c) displacing the water present in the hydrogel by means of a low- boiling liquid which is inert to the pigment-containing silica gel, d) heating the liquid-containing silica gel thus obtained with complete covering with the liquid to supercritical conditions and e) subsequently removing the liquid from the solid by flash evaporation at supercritical temperature.
